Description

Cantilever for installation of lighting fixtures}

In various art performances such as plays, musicals and concerts, stage lighting is one of the most important factors to maximize the effect of the performance. Therefore, a number of lighting fixtures are used in a permanent performance hall or exhibition hall to create more diverse lighting effects. These lighting fixtures vary in number, type, and layout depending on the stage shape, performance characteristics, and types of exhibits.In a room such as a permanent performance hall, a large number of structures are called fly ducts, which are fixed to the ceiling. Lighting fixtures are installed side by side in the horizontal direction.

However, in order to temporarily install a performance hall outdoors or temporarily install a lighting fixture in a room without fly duct facilities, a prop such as a lighting tower is set up, and various lighting fixtures are installed there. However, since most of the pillars are installed in the vertical direction, in order to install the lighting fixtures, horizontal supports are installed at a suitable height between both pillars, and then various lighting fixtures are hung on the horizontal supports.

In this case, there is a problem that it takes a lot of time to install the luminaire because the horizontal support is installed by cutting a conventional pipe to a predetermined length and fixing both sides with a wire or a string between two longitudinal struts.

Therefore, the problem to be solved in the present invention is to provide a cantilever for installing the lighting fixtures designed to quickly and safely install a variety of lighting fixtures in the prop (P) standing vertically on the temporary performance hall or stage.

The cantilever for installing the luminaire according to the present invention is to be installed to mount the lighting device on the strut (P), which is erected in the vertical direction, and a support rod extending laterally from the strut (P); A hook formed of a metal material having a connecting portion to which the first end of the supporting rod is coupled, and a C-shaped supporting portion for supporting the support rod so as not to be separated in the horizontal direction by winding the support P in the circumferential direction; A clamp formed in one body with the hook, the clamp being installed obliquely downward from the connection part to detachably fix the support rod to the support P in a state spaced below the support part; And a control unit.

The clamp may include a bracket extending obliquely downward from the connection part; A fixed arc member fixed to a lower end of the bracket to surround the post P in the circumferential direction; A rotating arc member having a first end hinged to the first end of the fixed arc member and surrounding the post P in the circumferential direction; A screw rod having a first end hinged to a second end of the fixed arc member, the second end passing through a second end of the rotary arc member; A tightening nut installed at the second end of the screw rod to tighten the second end of the rotary arc member; .

The cantilever for installing the lighting fixture according to the present invention has the effect of quickly and safely installing various lighting fixtures on the shore (P) which is vertically erected on the ground or the stage.

In addition, the cantilever may be used for installing a facility such as a road sign or a billboard as needed.

1 is a view showing a state in which the cantilever beam according to the present invention is installed on the support (P),
2 is a view showing a state in which the cantilever is separated.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings. In the present invention, for convenience, the vertical direction will be described by dividing the pillars vertically erected vertically, and the direction crossing the pillars P horizontally will be referred to as a 'horizontal direction'.

Also, in one component having a predetermined length, either end of both ends is referred to as a 'first end' and the opposite end is referred to as a 'second end'.

The cantilever beam for installing the luminaire according to the present invention is used for mounting a luminaire used for stage lighting on a strut (P) standing vertically on the ground or the stage. At this time, the pillar (P) is installed in the indoor or outdoor performance hall or exhibition hall, for example, may be an illumination tower. However, such use does not limit the scope of the present invention.

The cantilever beam for luminaire installation according to the present invention includes a support rod 10, a hook 20, and a clamp 30 as shown in FIGS. 1 and 2.

First, the support rod 10 is installed so as to extend in the horizontal direction from the support (P) has a predetermined length, there is no particular limitation, it is preferable that it is a circular pipe. The support rod 10 is used for mounting various lighting fixtures used for future stage lighting, and may be configured to have a suitable length and diameter as necessary.

Next, the hook 20 is coupled to the first end of the support rod 10 so as to walk around the pillar P in the circumferential direction so that the support rod 10 does not deviate from the pillar P in the horizontal direction. It has a function to serve, and has a tubular connection portion 21 to which the first end of the support rod 10 is coupled, and a C-shaped support portion 22 that surrounds the strut P in the circumferential direction.

The support portion 22 should be wider than the diameter of the support (P) so that the support (P) in the radial direction through the C-shaped inlet, and the support (P) in the circumferential direction It is desirable to have a size of an arc that surrounds about half. If the spacing of the inlet is too wide compared to the diameter of the strut P, or if the arc size is too small, there is a fear that the support force for the strut P is weakened.

Finally, the clamp 30 is installed obliquely downward from the connecting portion 21 to separate the supporting rod 10 from the support portion 22 in a state spaced apart from the supporting portion 22 below the hook 20. It functions to fix it as much as possible.

Although the material of the hook 20 and the clamp 30 is not particularly limited, it is preferable that the hook 20 and the clamp 30 are made of metal so as to support the weight of the lighting fixture mounted on the support rod 10. In addition, the hook 20 and the clamp 30 may be molded in one body and have a structure in which the first end of the support rod 10 is inserted into the connection portion 21. The clamp 30 may be any of the pipe clamps conventionally used.

1 and 2 illustrate a clamp 30 according to an embodiment of the present invention, and includes a bracket 31, a fixed arc member 32, a rotating arc member 33, a screw rod 34, and a tightening nut. It consists of 35. The bracket 31 extends obliquely downward from the connection part 21 and has a structure that forms an acute angle with the support part 22.

In addition, the fixed arc member 32 is fixed to the lower end of the bracket 31 is configured to partially surround the strut P in the circumferential direction. The rotary arc member 33 is configured to partially surround the strut P in the circumferential direction with a first end hinged to the first end of the fixed arc member 32. Thus, when the fixed arc member 32 and the rotary arc member 33 are combined, it is preferable to enclose the strut P about 1/2 to 2/3 in the circumferential direction.

The screw rod 34 has a first end hinged to the second end of the fixed arc member 32, and the second end of the screw rod 34 is the second end of the rotary arc member 33. It is installed to penetrate through. The tightening nut 35 is installed at the second end of the screw rod 34 and configured to tighten the second end of the rotary arc member 33.

At this time, a through hole (not shown) through which the second end of the screw rod 34 penetrates may be formed at the second end of the rotary arc member 33, but the rotary arc member 33 is shown in FIG. It is preferable that the 2nd end of is divided so that it may be comprised so that the 2nd end of the said screw rod 34 may go in and out.

Referring to the method of using the cantilever for installing the lighting fixture according to the present invention, first to hang the support 22 of the hook 20 to the support (P) and to place the support rod 10 at an appropriate height, and then of the support 22 The clamp 30 is disposed below and the fixed arc member 32 and the rotary arc member 33 are wound in the circumferential direction of the support P.

Then, the second end of the screw rod 34 is inserted into the second end of the rotary arc member 33, the tightening nut 35 is tightened to secure the clamp 30 to the support P, and then the support rod (10) Install various lighting fixtures.

As such, when the lighting device is installed on the cantilever beam according to the present invention, a significant bending moment and shear force are generated at the fixed end of the support rod 10 by the load of the light fixtures, and at the fixed end of the support rod 10. Since the installed clamp 30 supports the support P at an angle from below, the hook 20 holds the support P firmly from above, effectively dispersing the bending moment and the shear force, thereby making the support rod 10 more stable. It can support.

On the other hand, in order to separate the support rod 10 from the support (P) or to move the position of the support rod 10, first loosen the tightening nut 35 of the clamp 30 from the second end of the rotary arc member 33 The second end of the screw rod 34 is separated, and the rotary arc member 33 is flipped back to dismantle the clamp 30 from the support P.

After dismantling only the clamp 30 in this way, even if the support portion 22 of the hook 20 is held on the support (P), the height of the support rod 10 may be adjusted, or the support rod 10 may be rotated. .

The cantilever beam according to the present invention can be used for installing various lighting facilities in stadiums, sports facilities, parks, roads, etc. in addition to the use of stage lighting in temporary performance halls or exhibitions. It can also be used to install facilities.
